Screen Filter: Adjusts Screen Color Temperature for Comfort
Open source software for Windows, Mac, and Linux to reduce eyestrain by lowering brightness and filtering out blue light.
What is Screen Filter?
Screen Filter is a free, open source application available for Windows, macOS, and Linux that helps adjust a computer screen to make it more comfortable to look at. It works by overlaying the screen with a colored filter that can lower brightness levels and filter out blue light wavelengths that can disrupt sleep cycles.
Some of the main features of Screen Filter include:
- Lowers screen brightness below your computer's built-in minimum level, helping to reduce eyestrain in dim lighting.
- Tints your screen amber or reddish-orange to limit blue light exposure. This helps regulate circadian rhythms and makes screens easier to look at at night.
- Lets you set a custom timer to have the filter automatically enable and disable at set times of day.
- Runs in the background passively so you can adjust your computer's screen temperature for all your apps and anything displayed on the screen.
- Completely open source and free software published under the GNU GPLv3 license.
By adjusting color temperature and brightness, Screen Filter aims to prevent disrupted sleeping patterns and eye strain associated with looking at bright, blue-light emitting screens in the evening or nighttime. While apps like f.lux serve a similar purpose, Screen Filter gives users more manual control and works system-wide to filter everything showing on a screen. Its customization options and open source nature make it popular with users who spend a lot of time looking at displays.
